I have to assume that you did not watch the game after reading your comments.
Why would Cassell try to throw to Moss and a double coverage gameplan when Watson was wide open for the majority of the night and Welker was allowed to run into the middle of the field with only single coverage????? Answer, he would not, instead opting for throwing for a mere 400 YARDS. Only an absolute nimrod would try to force into double coverage when there are other receivers not being covered, period.
With the Safety so concerned about Moss, it left the middle of the field wide open the entire game, hence the reason why Cassell lead the Pats in rushing yardage. Once again, why force into double coverage when the Jets are giving you almost eight free yards.
If you are claiming that Law shut Moss down, someone else could easily claim that Law was such a liability that the Jets were forced to provide help and the Defense was shredded bacause of it.
By the way, there were several times where Moss had broken containment and Cassell just could not get him the ball due to being horrible at throwing over twenty yards. He overthrew Moss once on a walk-in touchdown.
